Abstract

Un procedimiento para la producción de piezas de moldeo espumadas que comprende las etapas de proporcionar un molde (1) e introducir una mezcla de reacción que forma espuma (6) en el molde (1), en el que la mezcla de reacción que forma espuma (1) es introducida en el molde (1) bajo presión de inyección constante y en una cantidad que es variable en el tiempo. La cantidad introducida de la mezcla de reacción que forma espuma es variable en el tiempo por la variación de la potencia de salida de un motor de bomba, que actúa en la mezcla de reacción.
